I have a document in AD with multiple artboards. Each artboard is an export slice.
If I move one artboard to a most left or top position in the document (the artboard's position is shown with a negative x,y during drag) then that position will be the new 0,0 position and all other artboards will be updated accordingly. But all the export slices will not be updated to the new coordinates! Therefore they are all wrong afterwards :-(
Best,
Rudi
